Liebert PSI is a compact, line-interactive UPS system designed especially for IT applications such as network closets and small data centres. It provides reliable power protection for servers, critical nodes, network workstations, large network peripherals, network routers, bridges, and other electronic equipment.

The flexible design of Liebert PSI allows the UPS to be configured as a self-standing tower or to be rack-mounted within a 2U space.

The UPS features an innovative line-interactive design incorporating buck/boost automatic voltage regulation technology.

Due to the size, weight and delicate nature of Data and Server Cabinets, specialist couriers are required so they arrive on site in pristine condition.

We do our utmost to bare the delivery costs meaning we can deliver your cabinet free of charge to most areas, unfortunately there are some areas of the UK we are charged a lot more to deliver to and whilst we absorb as much of this cost as we viably can in certain cases we have to pass on some of these costs. Below is a list of these areas and the additional costs of delivery per cabinet.
